Description
The utility model relates to green technology, and is specifically a kind of with the device of air dissolves in water.
When disposing of sewage, need utilize air soluble method that water is carried out molten gas with the air supporting method.The main points of air soluble method are to tell a part through the clear water after purifying in the air flotation pool, to pump in the dissolving with reflux pump, and make it to keep certain pressure, to feed the high slightly pressurized air of pressure simultaneously.Water needs to be detained for some time in dissolving, and air can be dissolved in the water gradually by diffusion.The pressure water of molten water air is called dissolved air water.Dissolved air water suddenly is decompressed to normal pressure after discharging, air soluble in water becomes the supersaturation attitude suddenly, so in water, evaporate rapidly, form small bubble, this water that is full of microbubble is imported air flotation pool, mix with the sewage after the dosing flocculation, microbubble can combine with flocs unit, and with its picking-up, floating to water surface formation scum silica frost, use the Scraping device descum, sewage just is purified.
The dissolved-air rate of dissolving is high more, and the microbubble concentration after not only discharging is high more, and the degree of supersaturation of molten gas is also big more when discharging, the speed that molten gas evaporates in water is faster, the microbubble that forms is directly through littler, and the two all can improve air flotation effect, and purification rate is improved.
But the present dissolving that uses, its molten gas principle is based on the diffusion of gas molecule, thereby dissolving is quite big, and molten gas efficient but has not high.
The purpose of this utility model is that design is a kind of simple in structure, the high Gas dissolving pipe of molten gas efficient.
Its main technical schemes comprises a body and is installed in clear water inlet pipe and dissolved air water outlet pipe on this body, air distribution plate is arranged in body, the two ends of body connect end cap, a gas ejector pipe is arranged on the flow deflector in air distribution plate, at the uniform vertically micropore of a side of this gas ejector pipe, opposite side connects inlet pipe, and wherein micropore and inlet pipe lay respectively on two planes of flow deflector, and the other end protruded tube of inlet pipe is external; One segment distance n is arranged between the medullary ray of clear water water inlet pipe and the medullary ray of body, outward-dipping angle α is arranged between the medullary ray of clear water inlet pipe and the transverse section of body, air distribution plate is positioned at the opposite of clear water inlet pipe, and and the inwall of body between angle β is arranged, the two ends of air distribution plate utilize fixed link to be installed in the inwall of body respectively: inlet pipe is positioned at the middle part of gas ejector pipe, the outer end of inlet pipe is positioned at the saddle flange on the outer wall that is installed in body, and between inlet pipe and saddle type method are put, sealing-ring is set, chew at the end of saddle flange connection Intake Cover and gas, between Intake Cover and saddle type method gas, gasket is set; In the clear water inlet pipe, the jet pipe of tubular is connected with body, and the upper end of jet pipe connects special-shaped hydraucone, and at the bell-mouthed end of abnormity joint flange, the outside inwall of jet pipe and the inwall of body are tangent; The transverse shape of flow deflector can be plate shaped or arc in the air distribution plate, if during arc, the connection transverse slat at its two ends also is an arc, between the port of clear water inlet pipe and body, utilize to take over and be connected ball valve, manage intravital air distribution plate and can install 1, two or more, stagger mutually in the installation site of every air distribution plate.
The utility model has the advantages that molten gas efficient height, the recirculation water that comes when the reflux pump pump is from jet pipe when α and certain speed are spurted in the body at a certain angle, in the L section, because the shock action of jet pipe current is managed intravital water and begun to rotatablely move as volution on whole cross section.When being used as water that spirrillum rotatablely moves and being advanced into the air distribution plate position, its fluidised form is as shown in figure 10: the outer current between tube wall and the air distribution plate keep corkscrew motion substantially, and at C point place, the water that is rotating is because of being subjected to stopping of flow deflector, be forced to change direction, be close to the air distribution plate motion.Tangential speed is bigger at A point place.At this moment, spray in the micropore of pressurized air with very high speed gas ejector pipe on air distribution plate, the place enters in the water body at the A point.If micro-pore diameter, pitch-row and compressed air pressure, flow are selected proper, the micro-air stream that enters in the water will be dissolved rapidly fully, the water that dissolves in behind the air is withdrawn the A point rapidly, the water that its position is not dissolved in air immediately replaces, this has just realized water--sharp acute change that the gas contact is mutual, thus accelerated molten gas process greatly.
Because whenever to revolve the water layer that dissolves in air of turning around very thin for water body in the pipe, so air distribution plate must have certain length, and setting angle β arranged, so, along with the spirrillum of water body is rotated, air is able to dissolve in continuously layer by layer.
The setting angle α of jet pipe has determined the helix angle of water body spiral motion in the gas, generally must get α≤β.So, because the reflex action of air distribution plate, the water body of air distribution plate inboard will not advance along the body axial direction due, sometimes retreat slightly on the contrary, that pushes ahead only is the ring-type water layer between inside pipe wall and the air distribution plate, this water layer spirrillum is advanced into body solution water out place, discharges body, enters reliever.Be not difficult to find out that the water that A point place must have been dissolved in air is directed at the outer ring, the flow deflector of air distribution plate upside has played this effect.Owing to produce negative pressure near the existence of the flow deflector of air distribution plate upside, B point, add the tangential speed height of A point place water, dissolved in the water behind the air and dashed to the outer ring.Between the ratio of choose reasonable α and β, air distribution plate width H, air distribution plate and the inboard wall of tube body apart from △, the water that can guarantee to dissolve in behind the air arrives inboard wall of tube body at D point place.
At D point place, owing to sneaking into of A point place current, External Cordon Line speed will increase, and the kinetic energy of its increase is passed to heart portion water body gradually in rotary course, and the water body rotation of heart portion is quickened, and External Cordon Line speed is to recovering normal near the E point again.It is proper only to need each parameter to select, and can make the current tangential speed at A point place on each cross section constant substantially, guarantees that promptly the resistance in each micropore aperture of air distribution plate gas ejector pipe is constant substantially, that is guarantee that the jet amount of each micropore is constant substantially that molten gas effect reaches optimum value.
Pipe diameter φ, length L, jet pipe flow velocity V, jet pipe installation angle α, air distribution plate is to the distance 1 of jet pipe, air distribution plate length, air distribution plate and inboard wall of tube body be apart from △, air distribution plate width H, air distribution plate setting angle β, micropore size and pitch-row, the radius-of-curvature of arc air distribution plate are the important parameters of this dissolved-gas pipe.
